UNITED STATES PATENT HENRY M. QUAOKENBUSH, OF HERKIMER, NEW YORK.

. IMPROVEMENT IN AIR-GUN DARTS.

Specification forming part of Letters Patent No.l59,35 l, dated February2, 1875; application filed November 11, 1874.

To all whom it may concern:

Be it known that I, HENRY M. QUAGKEN- BUsH, of Herkimer, Herkimercounty, New York, have invented a new Manufacture of Air-Gun Darts andother articles, of which the following is a specification:

The drawings acccompanying this specification represent, in Figure 1, alongitudinal section, and in Fig. 2 a cross-section, of a dart embodyingmy improved construction. Fig. 3 represents a modification incross-section of my invention, to be hereinafter explained.

My invention consists of an air-gun dart havinga plug, pin, or otherobject, of metal or a sufficiently hard material, Within the tube, whichconstitutes part of the dart, and inserting between such plug and theinner periphery of such tube the strands of silk, bristles, or othermaterial of which the tuft of the dart, or the body of a brush, &o., maybe composed, the result being that the plug or core, being driven withgreat force into the tube, securely retains the tuft or bristles thereinby friction or compression.

In these drawings, A represents the metallic portion or head of thedart, consisting of a tubular body, B, and a pointed head, 0, after theordinary manner of producing such articles. The tuft of fibrous materialwhich steadies the motion of the projectile is shown at D, and it is tothe method of securing this tuft to or within the body of the dart thatmy invention relates.

Heretofore a cord or thread has been wound about one end of this tuft,and it has then been secured within the tube B by shellac or othercements and, as a consequence, it frequently became detached.

In carrying out my invention, I procure a quantity of fibrous materialof sufficient amount as, when doubled, to tightly fill the tube B, and.of a length double that heretofore used, and I double this material, andinclose within the bend or fold a small pin, a, or plug of metal orother substance, of alength or size equal to, or about so, of the innerdiameter of the said tube B. 1 then drive the pin transversely into thetube B, and down to, or nearly, its bottom, the fibrous material being,as a consequence, carried with it, and securely confined in place. Thelength of the pin is such as to require considerable force in driving itto place; and when thus driven itwill never be displaced, except by theexertion of great power, and the probable ruin of the dart.

Under the method heretofore practiced individual strands of the tuftbecome loose and reduced in size, and escape from the tube. By my methodof construction single strands cannot escape, and the whole tuft is heldfirmly in place.

I claim 1 An air-gun dart provided with a tuft secured in the tube atthe rear end of the dart by a plug or core driven in said tube, as shownand set forth.
